The polyhalogenated benzimidazole nucleosides 2,5, 6-trichloro-1-(beta-D-ribofuranosyl)benzimidazole (TCRB) and the 2-bromo analogue (BDCRB) were synthesized in our laboratory and established as potent and selective inhibitors of human cytomegalovirus (HCMV) with a novel mode of action. In an effort to study the behavior of the key substructure in a dimensionally extended manner and probe the spatial
在我们的实验室中合成了多卤代苯并咪唑核苷2,5、6-三氯-1-(β-D-呋喃呋喃糖基)苯并咪唑(TCRB)和2-溴类似物(BDCRB),并将其作为人巨细胞病毒的有效和选择性抑制剂( HCMV)具有新颖的作用方式。为了研究关键亚结构的行为,在尺寸上扩展并探究目标酶的空间限制,一系列了2-取代的6、7-二氯-1-(β-D-呋喃呋喃糖基)制备了萘酚,2,3-二咪唑和2-取代的6,7-二氯咪唑-4、5-喹啉的N1-和N3-核糖核苷。核苷6、7-二氯-1-(β-D-呋喃呋喃糖基)咪唑4,5-bquinolin-2-one和6,7-二氯-3-(β-D-核呋喃糖基)咪唑-4,5-选择了bquinolin-2-one,并将其用作咪唑4的关键合成中间体,5-喹啉系列。对化合物针对HCMV和1型单纯疱疹病毒的活性进行评估后发现,TCRB的三氯类似物(2a,3a)对HCMV的活性与TCRB几乎相同,但具有更高的
